BACKGROUND OF THE INVENTION

[0001] 1. Field of the Invention

[0002] The present invention generally relates to a packaging structure. More particularly, the present invention relates to a collapsible box.

[0003] 2. Description of the Related Art

[0004] Cardboard boxes are commonly utilized as containers and are generally available in many sizes and shapes. Many cardboard boxes are fully constructed by box manufacturers and delivered to customers as non-foldable boxes in ready-to-use forms. However, there are several disadvantages of a non-foldable cardboard box because the three-dimensional structure requires a large amount of space for transportation and storage, resulting in various economic inefficiencies. At the same time, an empty cardboard box may be easily damaged during transportation from the box manufacturer to its customers.

[0005] Foldable cardboard boxes, especially when designed as flat sheets, improve the storage and transportation inefficiencies. However, foldable cardboard boxes generally require several steps of manually folding and tucking various parts of the cardboard box to construct the box for use. Additionally, an adhesive (e.g., glue and/or tape) may be required to hold the foldable box after being constructed. However, these manual steps of constructing a foldable box generally require tremendous time and labor costs. For example, additional time spent to make a box by a store clerk who is completing a purchasing transaction results in generally unacceptable delays and inefficiencies at the check-out register. Such delays and inefficiencies may be reduced if the foldable boxes are made ahead of time so that the boxes are ready for use. However, the storage space requirements of fully constructed boxes again may present problems.

[0006] Therefore, there remains a need for a packaging structure which is easily transformed from a unconstructed form to a usable box. There also remains a need for a packaging structure which provides improved storage and transportation efficiencies.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

[0017] Embodiments of the invention generally provide packaging structures which are easily transformed from a unconstructed form to a usable box and provide improved storage and transportation efficiencies.

[0018]FIG. 1 is a top view of a collapsible box in a flat position according to one embodiment of the invention. The exemplar collapsible box described herein can be collapsed down to substantially flat layers of card board and may be further folded to improve efficiencies in storage and transportation of large quantities of the collapsible boxes. Although a rectangular collapsible box is illustrated, collapsible boxes having other shapes are also contemplated. Generally, the collapsible box 100 comprises a top panel 110, a back panel 120, a bottom panel 130, a front panel 140, a left side panel 150 and a right side panel 160. As shown in FIG. 1, the top panel 110, the back panel 120, the bottom panel 130 and the front panel 140 are foldably connected in sequence. In an unconstructed form, the panels provide a substantially flat layout with the side panels 150 and 160 disposed as a top layer. The top panel 110, the back panel 120, the bottom panel 130 and the front panel 140 forms a bottom layer (or main body layer).

[0019] In one embodiment, each panel may comprise medium or heavy weight cardboard, and sheets of paper (relatively much lighter weight compared to the cardboard) may be glued to the panels, with small gaps between adjacent panels (e.g., {fraction (1/32)} to ⅛ inch gaps for {fraction (1/16)} inch thick panels), t o provide the foldable connections between the panels. Alternatively, the panels may be taped together by strips of plastic or paper tapes to provide the foldable connections between the panels. In one embodiment, for a rectangular box as shown in FIG. 1, foldable connections 170 exist between a bottom edge of the front panel and a front edge of the bottom panel, between a bottom edge of the back panel and a back edge of the bottom panel, between a back edge of the top panel and a top edge of the back panel, and between a bottom edge of each of the left and right side panels and the left and right edges, respectively, of the bottom panel.

[0020] A plurality of connectors 180 are disposed to connect the side panels 150 and 160 to the front and back panels 140 and 120. The connectors 180 facilitate lifting of the front and back panels 140 and 120 toward an upright position when the side panels 150 and 160 are being lifted to an upright position. In one embodiment, each connector 180 comprises a first and a second triangular panels 182 and 184 which are foldably connected to form a substantially square-shaped panel with a diagonal foldable connection 186. The first triangular panel 182 is fixedly attached (e.g., glued) to the interior surface of the front panel (or back panel), and the second triangular panel 184 is foldably connected to a side edge 190 of a side panel. In another embodiment, each connector 180 comprises a triangular panel 182 having a first side foldably connected to a side edge 190 of a side panel and a hypotenuse edge foldably connected to an interior surface of the front panel 140 (or back panel 120).

[0021] The collapsible box may also include an enclosure flap 200 which is foldably attached to a front edge 112 of the top panel 110. A releasable fastener 210 may be attached to the enclosure flap 200 and the front panel 140 to facilitate closure of the collapsible box 100. In one embodiment, the releasable fastener 210 comprises a magnetic fastener set (e.g., a set of two magnets or a set of a magnet and a metal piece). Other releasable fasteners are contemplated for releasably holding the enclosure flap (or the top panel) against the front panel.

[0022] To change the collapsible box 100 from a flat layout to a three-dimensional box, a user may lift the side panels 150 and 160 to an upright position. FIG. 2 is a perspective view of a collapsible box 100 with side panels 150 and 160 in transition to an upright position according to one embodiment of the invention. As the side panels 150 and 160 are lifted, the front panel 140 and the back panel 120 are concurrently lifted because of the connectors 180 between the side panels 150 and 160 and the front and back panels 140 and 120.

[0023]FIG. 3 is a perspective view of a collapsible box 100 with side panels 150 and 160 in an upright position according to one embodiment of the invention. With the side panels 150 and 160 held in the upright position, the collapsible 100 box may be filled with one or more objects to be stored in the box. For example, the collapsible box may be utilized in a gift shop, and a store clerk may place one or more purchased gift items into the collapsible box. The collapsible box 100 may include a decorated exterior, and additional gift wrapping would not be necessary, saving time and money for both the merchant and the customer. The collapsible 100 box may also be decorated with a store's emblem, logo or a trademark.

[0024] In another embodiment, the collapsible box 100 may be folded from a flat layout to a compact position to further facilitate storage and transport of large quantities of collapsible boxes. FIG. 4 is a perspective view of a collapsible box 100 in transition from a flat layout to a compact position according to one embodiment of the invention. To facilitate folding of the collapsible box 100, the foldable connection 170B between the back panel and the bottom panel may be extended to provide a wider gap which accommodates for the combined thickness of the side panel (one of 150 and 160) and the connector 180. In the compact position, a plurality of collapsible boxes are easily stored and/or transported, increasing efficiencies in storage space requirements and transportation costs.

[0025] Although the described embodiment illustrates a rectangular box, it is contemplated that boxes having other shapes may be constructed utilizing connectors adapted to lift one or more panels as a user lifts one or more other panels foldably connected to the connectors. Furthermore, the orientation of the collapsible box as described is illustrative of one embodiment of the invention, and various orientations of the collapsible box are contemplated to accommodate the intended usage of the box.
